Abstract: The invention is directed to an integrated dual imaging detector on a single silicon chip comprising a beam interleaving polarization analyzer bonded to a charge-coupled device, serial shift register and associated image transfer circuitry, analog signal processors, and analog-to-digital converters. The invention permits the simultaneous acquisition and processing of two polarization images of rapidly changing subjects.

Abstract: In a solar vector magnetograph for measuring solar magnetic fields including a telescope pointable to a solar zone and relay optics mounted there-behind, including a collimating lens, a quarter wave plate, a light polarizer, a beam expanding means, a narrow bandpass blocking filter to admit a narrow spectral band of polarized light, a reimaging lens to focus the resulting beam and an image receiver, the improvement provided is a solid Fabry-Perot etalon filter which is mounted between the blocking filter and the reimaging lens, such filter being of a desired refractive index and thickness so as to select a narrow band of the so-transmitted polarized light and to transmit same to the image receiver, all in order to isolate and record the emissions of atomic species and to infer the magnetic field at the solar zone.
